Sorry about this. It appears that some copies of Linux Format that have been sent out to subscribers haven't been printed properly, so some of the pages in the tutorial section don't have any black ink. The issue (LXF173) isn't on sale yet, so we don't know the extent of the cockup. If only a few copies are affected, we'll be able to send out replacement copies from our stocks here; if loads of copies are affected, we''l have to sort something out with the printer.
If you get sent one of the faulty copies, please email contact@myfavouritemagazines.co.uk and they'll be able to sort you out with a replacement.

I too received my copy of Linux Format #LXF173. All the named pages also missing in my copy. I emailed them and it has been confirmed that there is a printing issue. I have been advised that a replacement copy will be sent out to me asap. They are also making every effort to get the PDF version on-line today (Monday 17 June 2013)

My copy arrived with no apparent flaws in printing.
However, I was disappointed by the lack of content - I considered that I had the installation adequately covered by the wiki (which didn't write USB stick where SD Card was meant in several places - confusing when there is also an install process which ends up with most content on a stick and just sufficient to boot on the card).
I was hoping to get more insight into uses after the successful installation.

I've just reached the end of issue 173, which I bought from my local Sainsburys as I do every month (I know, I should subscribe...), and it is also missing the text from the pages mentioned above. As it has been three weeks now I doubt if Sainsburys will still have another copy and in any case their copies would all come from the same run.

I'm hoping that the Libre Office, Raspberry Pi, MariaDB and Cuda articles will be reprinted in LXF174, or at least be on the DVD.

Also hoping that LXF174 will be back over 100 pages as #173 was getting a bit thin for £6.49 over the counter, even if all the pages had printing on them.
